When Marshall was 6 years old, he learned how to ride his bike. When he first learned to ride, he had to concentrate on not falling and keeping his balance. Marshall, now 10 years old, does not have to consciously think about keeping his balance on his bike. Marshall's ability to do this is caused by the process of:

automatization.

Explanation:,

automatization in generally consider in child cognitive development  when she is 6 year old she has to focus, consider and observe the knowledge and skill pf riding, but as she grown up and riding a bike is part of her routine , so at age of 10 she has not to consider these details. as she is not learning stage, she already learnt it. So riding bike is become a automatic process for her.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
